Title: Gallium nitride semiconductor substrate and process for producing the same
Inventor: NAKAYAMA MASAHIRO
IPC: C30B29/38
Filed: 2004-08-06
Abstract: A processing-degenerated layer occurs when nitride semiconductor single crystal wafers are polished. Etching must be performed for removing the processing-degenerated layer. However, since nitride semiconductors are chemically inert, no appropriate etchant is available. Although potassium hydroxide and phosphoric acid have been proposed as an etchant for GaN, their power of corroding the surface of Ga is weak. For removing the processing-degenerated layer, dry etching with the use of halogen plasma can be conducted. Even Ga surface can be pared off by halogen plasma. However, the dry etching would cause a new problem of surface contamination by metal particles. Therefore, wet etching is performed by the use of HF+H2O2, H2 SO4+H2O2, HCl+H2O2, HNO 3, etc. having no selectivity, being corrosive and having an oxidation-reduction potential of 1.2 V or higher as an etchant.

Title: Hierarchical coding with multiple antennas in a wireless communication system
Inventor: MANTRAVADI ASHOK
IPC: H04B7/04
Filed: 2004-09-27
Abstract: Techniques are provided for performing hierarchical coding in a multi-antenna communication system (e.g., a SIMO, MISO, or MIMO system). At a transmitter, a base stream and an enhancement stream are coded and modulated separately to obtain first and second data symbol streams, respectively. The first data symbol stream is processed in accordance with a first spatial processing scheme (e.g., a transmit diversity or a spatial multiplexing scheme) to obtain a first set of symbol substreams. The second data symbol stream is processed in accordance with a second spatial processing scheme (e.g., transmit diversity or spatial multiplexing) to obtain a second set of symbol substreams. The first set of symbol substreams is combined (e.g., using time division multiplexing or superposition) with the second set of symbol substreams to obtain multiple transmit symbol streams for transmission from multiple transmit antennas. A receiver performs complementary processing to recover the base stream and enhancement stream.
